The Elinchrom Skyport radio slave kit operates on a higher frequency than PocketWizards and other radio slaves. It does so much stuff it's hard to remember it all. The higher frequency allows it to transfer more data and also means less chance of channel conflicts with other photographers at events. There are 8 available channels and the Skyport allows remote flash sync at up to 1/1000th of a second, depending on camera and flash capabilities.
